Accuracy.
By the substitution method By the elimination method By plotting them on a graph
Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
Explain the advantage and disadvantage of circle graph
A graph is a visual view of data; a table is the numerical view of data.
Depends on advantage compared to what. There may not be any advantage compared with representing data in graph form.
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
You will obtain a more accurate answer than is possible using graphical methods. It's faster and less work than using a table.

line graph
Displaying data in a graph allows for easier visualization and comparison of trends and patterns, making it simpler to understand complex information at a glance.
Explain the advantage and disadvantage of circle graph
The prime advantage is that you can show change or dependency between variables when using two (or more) dimensions rather than just a single magnitude.

Oh, dude, like, the substitution method is cool because you can easily solve for one variable and plug it into the other equation. But, like, it can get messy with fractions and decimals. The elimination method is great for getting rid of one variable right away, but it can be a pain to keep track of all those plus and minus signs. So, like, pick your poison, man.
You use algebra and solve the system(s) of equations using techniques such as elimination or substitution.
